BeziehungsReich is a relationship-focused book series and online resource exploring how personal identity, happiness, and difficult choices shape life as a couple. Across three volumes, it invites readers to consider whether they can be themselves in a relationship, what contributes to satisfaction and emotional well-being, and how to think about affairs without devaluing existing partnerships. The series presents these subjects through reflective questions, practical methods, and opportunities for self-exploration.

Visitors can learn about each book’s themes and approach, browse introductions and contents in the downloads section, and use a short questionnaire to identify which volume may suit them. Online versions of the books’ relationship tests can also be completed and evaluated with an access code provided in the book. The website offers a shop for ordering the books and individual evaluations, along with a video tour and an example couple who guide visitors through all three volumes. Additional resources include a discussion forum, relationship topics, and information for professionals using the books in coaching, counselling, or therapy.
